I would have said it was morning too JD, and the red sky warning is correct.
However, there is another version:
Red sky in the morning, sailors warning.
Red sky at night, sheperds house on fire
With regards to the colour differential, I also have photos of morning skies which are different from those in the photo and also yours too. Just two weeks ago I got some pics in the morning of sea and sky and the whole lot were a beauitful golden hue!!
I have seen a similar photo by the same guy as posted the one this week, and it's different also
Do you think he is a member of a camera club or something and is using filters and computer enhancement techniques
Or am I reading more into your finishing line than you meant
